One‐dimension (1D) TiO 2 nanorods (TiO 2 ‐N) has been fabricated via electro‐spinning method. The composites of 1D TiO 2 ‐N and graphite nanosheets, termed as (TiO 2 ‐N/G‐N), have been obtained by the physical doping method. The structure and properties of TiO 2 ‐N and TiO 2 ‐N/G‐N have been characterised by scanning electron microscopy, transmission electron microscopy, X‐ray diffraction, and Raman spectrum. Dye‐sensitised solar cells devices with TiO 2 nanoparticles, TiO 2 ‐N and TiO 2 ‐N/G‐N as the mesoporous scaffolds have been developed and investigated, respectively. Device 2 based on TiO 2 ‐N scaffolds showed short‐circuit current ( J sc ) of 5.57 mA·cm −1 , open‐circuit voltage ( V OC ) of 0.68 V, filling factor of 0.75, and the power conversion efficiency of 2.85%, respectively. Compared with device 2, device 3 based on TiO 2 ‐N/G‐N exhibited reduced photovoltaic properties.
